Senior Research Associate - Department of Nutrition

Title: Senior Research Associate

Department: Nutrition

School: Medicine

Location: BRB 939

Supervisor Name and Title: John Tilton, MD, Associate Professor



We currently have a Senior Research Associate position available in the laboratory of Dr. John Tilton at Case Western Reserve University. The Tilton laboratory is a collegial and well-funded lab investigating cutting-edge technologies for delivery of CRISPR-Cas9 genome editing complexes in vivo.

The successful candidate should hold a Ph.D. in biological sciences with research experience in molecular or cell biology, immunology, virology, or biochemistry. Working mostly independently, the Senior Research Associate will perform experimental work including PCR, recombinant DNA technology and cloning, cell culture, production and analysis of virus-like particles, western blots, gel electrophoresis, flow cytometry, and preparation of samples for mass spectrometry. The Senior Research Associate will also perform experimental work to develop and test strategies to deliver genome editing machinery to tissues in vivo in small animals. Experience with these techniques or animal work is desired. The Senior Research Associate will work closely with the principal investigator, laboratory members, and other individuals in the Department and School of Medicine. Generous financial compensation is provided in accordance with experience and qualifications. 



  1. Plan and carry out experimental work of a complex and non-routine nature in accordance with the research studies. Experiments will include polymerase chain reaction (PCR) and Gibson assembly cloning of DNA plasmids; mammalian cell culture work including isolation, passaging, and transfection of cell lines and primary cells; production and purification of HIV and virus-like particles; cell line and primary cell infection experiments; and analysis of cells using western blotting, mass spectrometry, flow cytometry, ELISA and other methodologies. (40%)
  2. Plan and conduct experiments aimed at developing strategies to deliver protein and RNAs – including CRISPR/Cas9-gRNA complexes – to tissues in mice. Techniques include tail vein injection, genotyping using PCR, use of isoflurane anesthesia machines, managing and maintaining records of the mouse colony including monitoring breeding, and analysis of delivery using small animal imaging techniques including bioluminescence, fluorescence, micro-CT, and/or single photon emission computed tomography (SPECT) imaging (30%).
  3. Assist the principal investigator with dissemination of the research findings including authoring manuscripts and preparing data (figures) for publication, presenting research updates in the form of poster or oral presentations and national and international meetings.  (10%)
  4. Maintain accurate data recording and note-taking for experiments conducted. Analyze data and present findings at meetings with the principal investigator. (10%)
  5. Contribute to the day-to-day function of the lab including training new staff on standard operating protocols, working with students, and assisting with laboratory maintenance and oversight and maintenance of scientific reagents. (10%)



  1. Perform other duties as assigned.



Department: Weekly contact with supervisor to discuss research. Daily contact with laboratory members including research associates and postdoctoral fellows, research assistants, and graduate and undergraduate students. Contact with other members of the Department when required for the effective completion of research objectives.

University: Occasional contact with lab personnel, department assistants, and principal investigators from other departments and centers across the CWRU campus, including particularly in the Departments of Molecular Biology and Microbiology, Pathology, and Genetics and Genome Sciences.

External: Contact with outside vendors as needed.

Students: Daily contact with student workers to assist with the training and oversight of students.



As the senior research associate becomes established in the laboratory, they may be assigned research assistants to help them with their research. In this case, the research associate will have supervisory responsibilities along with the laboratory supervisor (Dr. Tilton).



Experience: At least 5 years of research experience in cell or molecular biology, biochemistry, immunology, microbiology, or related fields.

Education/Licensing: Ph.D. degree in Microbiology, Immunology, Genetics, Biochemistry or other field in the biological sciences.
